Juan Martin del Potro has ruled himself out of Argentina's Davis Cup clash with Italy.
The 25-year-old said that he is "tired" of the Association Argentina Tennis, who he claims have been "two-faced" in releasing negative press following his decision to withdraw himself from competition throughout 2013.
The world number five will miss his country's world group first-round encounter, which will be played on the clay of Buenos Aires between January 31 and February 2.
In a statement sent to AAT president Arturo Grimaldi and team captain Martin Jaite, the 2009 US Open champion said: "I won't be [available] in this first tie to be played against Italy.
"I'm tired of being invited by email or messages and being pressured at the same time through certain media with stories about whether or not I'll play the Davis Cup, trying to make me look bad to public opinion.
"It seems to me a hypocritical two-faced stance, the same as last year when any reply or non-reply was quickly known by some journalists."
Del Potro opted against playing Davis Cup over the past year in order to concentrate on the ATP Tour.
